Combined module PV-Therm from WIOSUN® Clean energy and natural heat successful united
The lower the temperature of the photovoltaic module, the higher their output. This is a problem, especially in summer when outside temperatures are high. When the solar cells heat up, it inevitably leads to loss in performance. What is therefore, more obvious than to cool the modules in order to increase efficiency? This is precisely the secret of the PV-Therm module: it is cooled using a heat transfer fluid - thus increasing output. But there is more: at the same time, the heat generated through the cooling process can also be used, e.g. for water heating or to support heating systems.
Two technologies in one module
Experts have often complained that the two functions - solar heat and Photovoltaic - have too negative a mutual impact to allow adequate flow of energy and heat from the roof. This was a challenge for William Bihler from Solarzentrum Allgäu, who spent many years developing a combined module for WIOSUN GmbH & Co.KG that effectively combines the two technologies. In 2008, he was awarded the Bundespreis für hervorragende innovatorische Leistungen für das Handwerk (Federal award for outstanding innovations in industry and trade) for this development.
